Inhibition of Kv4.3 potassium channels by trazodone

Trazodone, a triazolopyridine antidepressant, is commonly used in the treatment of depression and insomnia. Kv4.3 channels are transiently, and rapidly, inactivating Kv channels that are highly expressed in cardiac myocytes and neurons. To determine the electrophysiological basis for the cardiac and neuronal actions of trazodone, we studied the effects of… CONTINUE READING
